Last week, at the end of June, Microsoft released KB5027318 Dynamic Update, labeled "critical" for Windows 11 version 22H2. The dynamic update helps to improve the setup process of Windows, generally when a new feature update initiates.

The support article for the new KB5027318 update says:

Unfortunately, confirmed same "error" here on my older laptop 🤷‍♂️
I recall in the past for me was possible to install this kind of Dynamic updates via either CMD, Powershell or Terminal on Windows 11.

I remember the last time the files downloaded from MS Update Catalog was a msi type so clicking on it will install straightaway. Not sure why MS changed to cab file now.

Microsoft details why your recent Windows 11 WinRE updates may have been failing
If you have noticed WinRE (Windows Recovery Environment) updates failing recently on your Windows 11 PC, there may be a reason. Microsoft published a guidance article recently explaining why it is happening and has also detailed how to deal with the issue.

The company says it has changed the way it delivers WinRE updates as they are being deployed via monthly cumulative updates through the Windows Update (WU) and the Windows Server Update Services (WSUS). As such sufficiently large Recovery Partition is required for this and in the case the partition does not have enough room, the update will fail and display the following error message "Windows Recovery Environment servicing failed." The tech giant writes:
Summary
Microsoft has changed how it updates PCs that run the Windows Recovery Environment (WinRE). WinRE will be updated using the monthly cumulative update. This change only applies to PCs that get updates from Windows Update (WU) and Windows Server Update Services (WSUS). This change starts on June 27, 2023, for the Windows 11, version 22H2 cumulative update.
Some PCs might not have a recovery partition that is large enough to complete this update. Because of this, the update for WinRE might fail. You will receive the error message, "Windows Recovery Environment servicing failed.”
